Which bracelet or watch of Xiaomi is more cost effective?

Thank you for your invitation. I recommend the NFC version of mi band 3. The price of NFC version is 199 yuan. The wristband and the host are designed the same as the mi band 3. Made of thermoplastic elastic material, which increases the design of release and loss. The screen adopts 0.78-inch organic light-emitting diode touch-sensitive display screen, which supports the display of WeChat. QQ, incoming calls, text messages, etc., but only pure black can be displayed. The screen supports up to 24 Chinese characters and wrist display. Support 50 meters waterproof, meet the needs of daily life! The battery is 1 10mAh, which can reach the battery life of 15 days. The NFC version has built-in NFC chip technology, which supports NFC brush bus cards and access cards. At present, the 3 NFC version of mi band has supported the city bus card and the transportation joint card, so it is very convenient to brush the bus and subway when traveling. In addition to supporting bus and subway card swiping, the mi band 3NFC version also supports the access card function, and the binding is simulated by the access card on the APP side. However, at present, only unencrypted access cards with the frequency of 13.56 MHz are supported in the market. In addition, bank cards with access card function and stored value consumption are temporarily not supported. On the whole, the mi band 3NFC version has a good performance in both appearance and function. At the end of recent years, Xiaomi Mall will definitely have various activities, hoping to buy this cost-effective bracelet at a good price. Finally, I hope my answer can help you!
